It’s finance provided to your business based on predictable income. The loan is typically repaid directly from future sales with low interest and rolling credit lines since you’re leveraging your future revenue.
Example 1 for ecommerce businesses
You have regular ecommerce sales via cards. The finance provider is able to easily see your track record and loan against that based on future predictions.
Example 2 for SaaS businesses
You have a SaaS or subscription business model and are able to use your history along with your predictable revenue to get access to capital, since you have a scalable asset larger loans might be available.
Example 3 for businesses that send large invoices
You send invoices to existing customers, but instead of waiting 30 days for these invoices to be paid you want them immediately credited by the finance provider.
